What furnace repair involves
Repairing a furnace properly means confirming why the part failed, not just that it failed. A flame sensor that fouls every winter is telling you something about combustion or filtration.
Diagnosis and repair of gas, propane and oil furnaces — ignition, flame sensors, blowers, boards and heat exchangers.
Common problems and warning signs
- Blower runs but the air is cold
- Furnace lights, then shuts down after a few seconds
- Clicking or repeated attempts to ignite
- Burning or hot-metal smell when it runs
- Thermostat calls for heat and nothing happens
How we repair it
We stock the wear items — ignitors, sensors, capacitors, limit switches, thermocouples — so a large share of no-heat calls get finished in one visit. Anything specialty gets ordered with a firm timeline, not a maybe.
When replacement makes sense
If the heat exchanger is cracked or the unit is past 20 years with repeated failures, we'll say so plainly and quote a replacement. If it has years left, we'll tell you that too — that's the more common answer.
Questions from Stillwater homeowners
- How long does a furnace repair take?
- Most are an hour or two once the diagnosis is done. Parts that have to be ordered are the main reason a job stretches past one visit.
- Is it worth repairing an older furnace?
- Often yes. Age alone doesn't condemn a furnace — a cracked heat exchanger or repeated major failures do.
